Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520442, here are decompositions:

  • 19 + 520423 = 520442
  • 31 + 520411 = 520442
  • 61 + 520381 = 520442
  • 73 + 520369 = 520442
  • 79 + 520363 = 520442
  • 103 + 520339 = 520442
  • 151 + 520291 = 520442
  • 163 + 520279 = 520442

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 520,442 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 520442 first appears in π at position 412,497 of the decimal expansion (the 412,497ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
